The Sun rises in the east (near arrow), culminates in ...
These angles are set on the compass for a chosen time of day, the compass base is set up level using the spirit levels provided, and then the sights are aligned with the Sun at the specified time, so the image of the Sun is projected onto the cross grating target. At this point the compass base will be aligned true north–south.
With the sun at your back, you can then safely view the projected image. Don't look at the sun through the pinhole. An eclipse projector can also be made with a cardboard box, a white sheet of ...
The time when the Sun transits the observer's meridian depends on the geographic longitude. To find the Sun's position for a given location at a given time, one may therefore proceed in three steps as follows: [1] [2] calculate the Sun's position in the ecliptic coordinate system, convert to the equatorial coordinate system, and

Only a few months remain until the astronomy event of the decade unfolds over North America as the sun, moon and Earth align to create a spectacular solar eclipse for a few brief minutes. Millions ...
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
An eclipse projector is an easy and safe way to view the eclipsed sun. Follow these instructions for creating your box pinhole projector. Using a pencil, trace one end of the box onto the white ...
